Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738842, here are decompositions:

  • 3 + 8738839 = 8738842
  • 5 + 8738837 = 8738842
  • 29 + 8738813 = 8738842
  • 41 + 8738801 = 8738842
  • 59 + 8738783 = 8738842
  • 83 + 8738759 = 8738842
  • 113 + 8738729 = 8738842
  • 131 + 8738711 = 8738842

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,738,842 and was likely granted around 2014.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 8738842 first appears in π at position 15,092 of the decimal expansion (the 15,092ordinal-suffix:nd digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
